Capability to encrypt or decrypt a file using a given key

NupurSood — Mon, 23 Aug 2021 10:16:00 GMT

Hello All

Is there a utility or code anyone is aware of that can help encrypt or decrypt a file (possibly excel with multiple tabs)

Thank You

Hi @NupurSood,

Check out the Utility - Encryption VBO on the DX. You can find it here.

Hello Eric

Thank you for your response. The DX asset shared seems to convert data items but I have excel files which I do not want to get as a string (due to formatting and amount of data). Would you have a suggestion to deal with a scenario like that where the complete file itself can be encrypted or decrypted

Regards

Hi @NupurSood,

If the contents of the file are text you could still use this VBO to encrypt/decrypt it. You would just need to read the contents of the file into a Text data item, encrypt/decrypt that text, and then write the contents back out to disk. Unfortunately, this VBO doesn't support working with binary data at the moment, so a typical XLS file would be an issue. I'm adding this as a new feature request for the VBO.

FWIW - There are File.Encrypt() and File.Decrypt() actions available in .NET that could be called from a code stage. There is a potential issue with those though as they are specific to the logged in user account. In other words, you don't provide a specific key. The Windows O/S decides on the salt and key based on the logged-in user. So if robot XYZ encrypted a file only robot XYZ would be able to decrypt it.
